Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480336, here are decompositions:

47 + 31480289 = 31480336
233 + 31480103 = 31480336
257 + 31480079 = 31480336
317 + 31480019 = 31480336
389 + 31479947 = 31480336
479 + 31479857 = 31480336
593 + 31479743 = 31480336
599 + 31479737 = 31480336

Showing the first eight; more decompositions exist.
